The application of extraocular muscle maximum standardized uptake value of 99mTc-diethylenetriamine pentaacetic acid orbital single photon emission computed tomography/computed tomography in the assessment of Graves' orbitopathy.

Department of Nuclear Medicine, Tianjin Medical University General Hospital, Tianjin, China.
Purpose: To study the feasibility and value of assessing patients with Graves' orbitopathy (GO) in 99mTc-diethylenetriamine pentaacetic acid (DTPA) orbital single photon emission computed tomography/computed tomography (SPECT/CT) with extraocular muscle maximum standardized uptake value (SUVmax).
Methods: A total of 235 patients underwent 99mTc-DTPA orbital SPECT/CT, including 176 patients with GO and 59 patients with Graves' disease (GD) as controls. The SUVmax of extraocular muscles, including right medial rectus muscle (RMR), right lateral rectus muscle (RLR), left medial rectus muscle (LMR), left lateral rectus muscle (LLR), was compared between groups, correlation analyses with clinical activity scores (CAS) and serological indices was performed, and the diagnostic efficacy was evaluated using receiver operating characteristic curves.

Purpose: Glomerular filtration rate (GFR) measured by dynamic renal scintigraphy (Gates method) is used in this study as the standard to investigate the applicability of two creatinine (Cr)-based GFR estimation equations in Chinese patients of different genders, age groups, and GFR stages diagnosed with neurogenic bladder (NB).
Methods: GFR values were measured using Tc-DTPA renal dynamic imaging, the new serum creatinine (Cr)-based chronic kidney disease epidemiology collaborative group (CKD-EPI) equation, and the equation for the estimated GFR of CKD patients in China, which were designated as sGFR, EPI-GFR, and cGFR, respectively. Pearson's correlation and linear regression were used to compare the differences, absolute differences, precision, and accuracies of the results of the two equations with sGFR to determine the formula offering better performance for the assessment of patients with NB.
Clinical surveillance of split renal function in kidney transplant recipients using Tc-diethylenetriamine-pentaacetic acid (DTPA) dynamic renal scintigraphy: preliminary findings and novel insights.

Background: En bloc kidney transplantation (EBKT) involves transplantation of two kidneys, the aorta, and inferior vena cava from a deceased pediatric donor into an adult recipient. Recent articles have shown that EBKT is associated with excellent long-term allograft performance and patient survival. Developmental differences exist between the two transplanted kidneys after EBKT, and it is crucial to assess split renal function.

Purpose: This study aimed to assess single kidney glomerular filtration rate (GFR) using various diffusion weighted imaging (DWI) models.
Methods: We reviewed adult patients with kidney diseases who underwent magnetic resonance imaging (MRI) examination from February 2021 to December 2023. DWI with 13 b-values was performed using 3.
Evaluation of split renal dysfunction using radiomics based on magnetic resonance diffusion-weighted imaging.

Center of Interventional Medicine, The Fifth Affiliated Hospital of Sun Yat-sen University, Zhuhai, Guangdong Province, China.
Background: Accurate and noninvasive assessment of split renal dysfunction is crucial, while there is lack of corresponding method clinically.
Purpose: To investigate the feasibility of using diffusion-weighted imaging (DWI)-based radiomics models to evaluate split renal dysfunction.
Methods: We enrolled patients with impaired and normal renal function undergoing renal DWI examination.
